Define the customer choice you are competing for
A useful brief starts with the situation in which a customer chooses between alternatives. Those alternatives can include an incumbent, a spreadsheet, a service provider or doing nothing. Listing companies that use the same category label can miss the actual competition.
Choose a decision the brief must support: which segment to pursue, which capability to build, how to explain a difference, or whether to enter a new channel. Keep the scope narrow enough that the research can change an action. State what is outside the brief, including markets or customer groups you have not examined.
Use a claim ledger rather than a feature scoreboard
For each alternative, capture the promised outcome, intended customer, route to purchase, visible constraints and source date. Label statements as directly observed, company-reported or inferred. An advertised capability is not evidence of frequent use, and a public price does not establish the amount a particular customer pays.
Preserve the exact comparison basis. If one offer bundles implementation and another charges for it separately, a headline price comparison can mislead. When documentation is unclear, record the uncertainty and the question you would need to answer. Do not silently give an unknown feature a zero.
Add cases that explain strategic choices
Cases can help you explore why a company narrowed its product, changed distribution or served a different customer. They complement current product research; they do not replace it. A historical case should have an event date and a note about what may have changed since.
Write a hypothesis for each apparent advantage. “This product wins because it has more features” is difficult to test. “The buyer avoids a separate implementation project” points to a concrete adoption mechanism. Look for counterexamples: when did a broader offer add complexity, or a narrower offer fail to meet a necessary workflow?
Deliver one decision page and an evidence appendix
The decision page should contain the customer situation, the closest alternatives, two or three meaningful trade-offs and a recommended next investigation or move. Put detailed feature observations and sources in the appendix. This lets a colleague challenge the reasoning without having to reconstruct your research.
A hypothetical team choosing its first integration might find that purchase approval, rather than feature coverage, is the limiting factor. It could investigate security-review effort before expanding the roadmap. This is an example of a possible inference, not a claim about any named competitor. Refresh the brief when the decision or the underlying offers change.
